Well, thanks for your interest, Pierre (you can ask us as many times as you want ;-)

Now that you ask... the module you are referring to is to be launched at the end of March, we are making the production boards after having tested the prototypes througly.

We are really very proud of it: it can produce >750W at 4ohm with no problem (more with lower loads) and it does it happily, with more than 30A peak current capability (electronically limited). Some features...

- Needs only a symmetrical supply. No need for input voltages, driver voltages, etc. It has a small switching DC/DC converter inside so power dissipation is extremely low (around 8W at +/-85V rails with no signal). So it is even more efficient than BP4078 but with more power.

- It has a header for what we call "input plug-in boards": small PCBs (10x20mm) that implement high pass filter, low pass filters, etc. and that very very cheap and easy to install. Making a triamp application is extremely simply by simply installing the suitable plug-in board in each amplifier.

- Small sized (80x95mm) rudged flat-base chassis, allowing top mounting on heatsinks (similar to VICOR half-brick dc/dc converters) and also the usual inserts for bottom mounting on a chassis, like in the BP4078.

...All this with the extremely good sound and abundant features of the successful BP4078: clipping indicator, on/off control, sync capability, lossless overcurrent, undervoltage and overvoltage protections, etc.

We have also designed a special version of our most powerful switching power supply, SPS80HV, to feed one of this modules at full power, with +/-85V rails.

We are sure you will find its price more than interesting as well...

Best regards,
Sergio

This is very encouraging. End of March - that's not too far off.

So for tri-amp setups, will you be offering lower powered versions of amps?

Sergio,

Just looked at your website...
(as end of march (and easter vacaton in spain :-) is approaching)

NO info on new amp as yet

Proposal:
Make a PACK "3 WAY SPEAKER" available
3 amps variable x-overs with PS

Regards
Reinhold

Yes... sorry...

Some unexpected delays due to big orders of other products. We have made a second version of the bigger amp and taken the opportunity of including some improvements...
I promise to post some photos when it is ready.

Thanks for the suggestion about the new pack. However, we currently don't have active xovers, they will appear as plug-in boards with the new modules.

12V to +/-60V 800W PSU is also on its way... we have a very well working prototype and final tests are being performing right now.

This is what Sergio from Coldamp said in this thread on the new amp:
(Before it was split to marketplace by netlist (in oversight I believe) )

====================
@Sergio:
Will we have a choice of xover boards ?
Will you support a xover socket for DIY xovers ?
Can we have documentation (info on interface & pins) ?
Can we at least select opamp of our choice ? (LM4562 anyone?)

Regards
Reinhold

P.S.: Q to Mod (Netlist) Is it always impossible to reply to a thread that has been split to Marketplace ? ... I had to continue like this here.

It should be possible to post here although they may appear with some delay.
